For a:v = d / Δt 
110 = 0.66 / Δt 
Δt = 0.66 / 110 
Δt = 0.006 s 
the period is: 
T = 2Δt 
T = 2*0.006 
T = 0.012 s 
the frequency is the inverse of the period. so: f = 1 / T 
f = 83.3333333 Hz (about; Hz = 1/s) 
b. T = 2π√(m/k) 
being the mass m = 200g = 0.2 kg = 2*10^-1 kg, π = 3.14 (about) and T = 0.012, k is equal to: 
0.012 = 6.28√(2*10^-1 / k) 
0.012 / 6.28 = √(2*10^-1 / k) 
0.00191082803 = √(2*10^-1 / k) 
2*10^-1/ k = 0.000003
2*10^-1 / k = 3*10^-6 
k = 2*10^-1 / 3*10^-6
k = 6.67*10^-5

now using hooke's law:
F = -kx 
F = - 6.67*10^-5* 3.3*10^-1
F = -2.20x10^-5m
F = -0.22 *10^4 N

If you place a paper clip very close to a magnet, the paper clip
Alik [6]
The answer is “D. all of the above”!

Metal from the paper clip is attracted to the magnet, so it will naturally move toward and stick to the magnet. This will cause the paper clip to temporarily become a magnet for other metals. I hope this helped!

Waves transport
Brilliant_brown [7]

Answer:

d)energy

Explanation:

Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.

Newton concluded that some force had to act on the moon because
Dimas [21]
Think in gravity, the moon is orbiting the Earth because of gravitational pull/force. Without this gravitational pull, the moon will just move in a straight line (Newton's first law).
